StockYard is a market simulator. The main idea behind the it is to build a virtual environment where various trading strategies can be tested. The system is implemented using a discrete event simulator and also uses the concept of time wraps. The system would mainly consist of multiple agents having different trading strategies incorporated in them and would compete against each other in the stock exchange. By building this system we hope to better understand the trading strategies and how they work in real world scenarios where external factors play a major role in the performance of an agent. Note: The current code is an initial prototype for a stock exchange market simulator.

How to Download & Install

Note: To install and run the command you need to have git installed in your computer. And have permission to the qsrgsim repository

Download & Setup

To download the repository type in the following command.

git clone

Alternatively, the repository can be downloaded as a zip file and unzipped in a convenient location.

several support packages are required beyond the ML4T virtual machine if using the  ML4T VM is convenient:
  pip install seaborn
  pip install bintrees

If starting from scratch one of the simplest install methods is to install Anaconda2 which installs python 2.7 and most of the packages with their dependencies. Then from the Anaconda prompt install seaborn and bintrees as above.

Also, the repository contains a file requirements.txt that list the various packages required and the entire group can be installed with the following command:

  pip install -r requirements.txt

How to Run

Step 1: Create necessary files

  • Create user directory under qsrgsim/ traders/
  • Create trade agent file as <user_name>
  • Create an under the same folder
  • the file format should be similar to qsrgsim/traders/vgeorge6/ which you can use as an initial reference for your work
  • The trading logic should be present in the "strat" method of <user_name>

Step 2: Add user agent based object using as an example.

  • Import the agent. For example:
 import traders.vgeorge6.vgeorge6_agent as vg
  • Create object and add it to the list of agents. For example:
 temp = vg.Trader(42, "vgeorge6"+str(42),,interval_time,kernel_1,"vgeorge6",wakeup_time,counter,volatility,stocks,initial_price,initital_qty)

Step3 : Run with a command line argument specifying the desired config file The program executes by running the stockyard file.
Go to the directory where the repository is present and type in the following command.

 python config4_new

Sample Output

The following is a sample output shown in the terminal:

Process finished with exit code 0

How to Configure

The configuration of the Agents and its properties are currently in a Q&A format as shown above.
We would be moving it to a properties file(csv/text format) from which the various key-value parameters can be read

Configuration Example

 Enter Exchange Name: NASDAQ
